You shouldn’t do Retinal Defocus Training more than 2 hours per day: Why?

FAQ n. 25. Power Vision System - How about it: you state that we shouldn’t wear special lenses more than 2 hours per day (in the intense program)! Why?

- Answers David De Angelis

The answer to your question is in the capability of our body to get used to different, induced stimuli: Exposing any physiological system to specifically and systematically repeated stimuli inevitably leads to changes in the that organ’s functioning. Regarding focusing, it means that specific exercises lead to modifications and consequent positive changes in focusing. So as to trigger the body’s capability of getting used to the induced stimuli, we need a stimulus of certain intensity, which could be empirically quantified as training time. Following the technique correctly, the most important factor is to calibrate the stimulus intensity so as to ensure it will be enough to trigger the adaptation without being excessive and therefore “unproductive.” It’s completely useless to overcome the adaptation threshold of any physiological system; therefore, it would be useless if someone trained with training lenses or did the exercises of ocular stretching for 24 hours. You can’t achieve improvements, since the body (and mind) have to take their own time for this adjustment or change to take place.

Imagine an athlete who is lifting weights and wants to increase his strength and muscular mass. He would practice according to his own training program for strength increase, lifting heavier and heavier weights (intensity—otherwise, after a while, it wouldn’t be a training stimulus at all). If he trained for 3 hours a day or 8 hours a day, his performance wouldn’t increase; excessive stimulus could even be self-defeating, jeopardizing recovery and body adjustment.

I’ve set up a 2-hours-daily training limit for the advanced program, since it’s estimated as a maximum stimulus to achieve the improvements fast and without jeopardizing your focusing ability.

The eyes need a maximum stimulus that is both suitable for training and also creates positive adaptation, like a positive focus change. The body needs time to get used to the exercises, as does your mind, which needs time to get used to perceiving the world that now appears clearer and with enhanced shadings. The visual process isn’t merely a physiological one, but one that involves deeper parts of the human psyche and our relationship with ourselves and with others. The way we relate to ourselves is with respect to our mind. Am I not said to be myopic-minded? The body is the soul’s mirror: when you understand it you will also understand how to work on your body. Your mental and emotional horizons are widening toward spiritual and holistic healing—and this involves all the states of “being” and not only the physical ones.
